High-performance analysis of polycyclic aromatic hydrocarbons by TD–GC–MS

In this application note, Markes International investigates the performance of Markes’ thermal desorption (TD) systems for the analysis of polycyclic aromatic hydrocarbons (PAHs) in air. They describe how sample re-collection can be used to conveniently check and validate recovery of high-boiling analytes through Markes’ TD system, therefore enhancing confidence in this fully automated and high-sensitivity alternative to conventional solvent-extraction methods.
